Definitions

  • the subject matter disclosed herein relates to air valves, and more particularly, to starter air valves for aircraft engines.
  • the aircraft engine may experience a bowed rotor condition which requires the aircraft engine to be cooled by drawing fan air through the aircraft engine by motoring the aircraft engine at a sub-idle speed.
  • Starter air valves are used within aircraft to selectively provide airflow to the air turbine starter of aircraft engine to rotate the aircraft engine at a desired speed. However, if the starter air valve fails to open, the manual override cannot provide a controlled amount of airflow to maintain the desired sub-idle speed to adequately cool the aircraft engine while avoiding damage from higher speed operation.
  • a disc assembly for use in an air valve with a valve body includes an outer disc with a concentric opening therethrough and an outer seal area, the outer seal area to selectively seal against the valve body, and an inner disc disposed in the concentric opening of the outer disc, the inner disc to selectively seal against the outer disc.
  • an air valve includes a valve body, and a disc assembly, including an outer disc with a concentric opening therethrough and an outer seal area, the outer seal area to selectively seal against the valve body, and an inner disc disposed in the concentric opening of the outer disc, the inner disc to selectively seal against the outer disc.
  • FIG. 1 shows an air valve 100.
  • the air valve 100 includes a valve actuator 102, a valve body 104, a manual override interface 106, and a butterfly valve assembly 110.
  • the air valve 100 can selectively provide airflow 101 to an air turbine starter of an aircraft engine.
  • the manual override interface 106 can be utilized to provide a desired airflow to the air turbine starter of the aircraft engine to motor the aircraft engine at sub-idle speed to cool the aircraft engine.
  • the air valve 100 allows for an operator to manually provide a desired amount of airflow to cool the engine in response to the bowed rotor condition while avoiding rubbing and other damage from an excessive aircraft engine motoring speed.
  • the airflow 101 flows through the valve body 104. Airflow 101 through the valve body 101 is controlled by the butterfly valve assembly 110 disposed therein.
  • the butterfly valve assembly 110 includes an outer valve disc 120 and an inner valve disc 130.
  • the butterfly valve assembly utilizes multiple valve discs sized for a desired flow area needed to achieve a desired flow rate.
  • the inner valve disc 130 is sized to provide a desired sub-idle motoring speed to cool an engine during a bowed rotor condition.
  • multiple valve disc sizes can be utilized to achieve the desired range of targeted flow rates and pressures.
  • by utilizing the outer valve disc 120 and the inner valve disc 130 manual operation of the air valve 100 can provide a desired flow rate while avoiding any potential damage.
  • the outer valve disc 120 is shown.
  • the outer valve disc 120 includes an outer seal area 119, a concentric hole 125, a shaft hole 122, and a through hole 128.
  • the outer valve disc 120 can seal the outer seal area 119 against the valve body 104, shown in FIG. 1 .
  • the outer valve disc 120 is rotated by an outer disc shaft 126.
  • the shaft hole 122 can receive the outer disc shaft 126. Torque can be transferred to the outer valve disc 120 through the pin 124. In the illustrated embodiment, the pin 124 is received in the pin hole 123.
  • the outer disc shaft 126 can be affixed in any suitable manner.
  • the outer disc shaft 126 is a spring loaded shaft to bias the outer valve disc 120 to a closed position. In the illustrated embodiment, the outer disc shaft 126 is coupled to the valve actuator 102, shown in FIG. 1 .
  • the valve actuator 102 can rotate the outer valve disc 120.
  • the valve actuator 102 can be any suitable actuator.
  • the valve actuator 102 can rotate the outer valve disc 120 to provide an airflow sufficient to provide a full start condition for an aircraft engine.
  • the valve actuator 102 to selectively rotate the outer valve disc 120 to a known position to provide a desired airflow to the air turbine starter of the aircraft engine to motor the aircraft engine at sub-idle speed to cool the aircraft engine.
  • the outer valve disc 120 includes a concentric hole 125 to allow the inner valve disc 130 therethrough.
  • the outer valve disc 120 can include a seal land 121 disposed around the edge of the concentric hole 125.
  • the seal land 121 allows for the inner valve disc 130 to seal against the concentric hole 125 and further transfer torque from the inner valve disc 130 to the outer valve disc 120.
  • the outer valve disc 120 further includes a through hole 128 to allow the inner disc shaft 136 to pass through the outer valve disc 120.
  • the inner valve disc 130 is shown.
  • the inner valve disc 130 includes a disc seal 138 and a shaft hole 132.
  • the inner valve disc 130 can seal the disc seal 138 against the seal land 121.
  • the disc seal 138 is any suitable sealing material, including any suitable elastomer.
  • the inner valve disc 130 is rotated by an inner disc shaft 136.
  • the shaft hole 132 can receive the inner disc shaft 136. Torque can be transferred to the inner valve disc 130 through the pin 134.
  • the pin 134 is received in the pin hole 133.
  • the inner disc shaft 136 can be affixed in any suitable manner.
  • the inner disc shaft 136 is a spring loaded shaft to bias the inner valve disc 130 to a closed position.
  • the inner disc shaft 136 passes through the through hole 128 of the outer disc 120.
  • the inner disc shaft 136 is coupled to the manual override interface 106, shown in FIG. 1 .
  • the valve actuator 102 may fail to actuate the outer valve disc 120.
  • the manual override interface 106 allows a technician to manually rotate the inner valve disc 130 and the outer valve disc 120.
  • the manual override interface 106 is a manual wrenching feature, allowing a technician to use a tool to manually rotate the inner disc shaft 136, and therefore the inner valve disc 130 and the outer valve disc 120.
  • the inner valve disc 130 is shown rotated 70 degrees by the manual override interface 106.
  • the concentric hole 125 allows flow therethrough to allow a desired air flow.
  • the resulting airflow can be provided to the air turbine starter of the aircraft engine to motor the aircraft engine at sub-idle speed to cool the aircraft engine in response to a bowed rotor condition.
  • the size of the inner valve disc 130 allows a technician to provide a desired flow rate when utilizing the manual override interface 106.
  • the inner valve disc 130 is shown rotated a total of 410 degrees by the manual override interface 106.
  • the inner valve disc 130 has rotated within the concentric hole 125 and has engaged the seal land 121 to transmit rotation to the outer valve disc 120 to drive the outer valve disc 120 open.
  • the outer valve disc 120 is rotated 70 degrees to open relative to the valve body 104.
  • the opening of the outer valve disc 120 allows flow through the valve body 104 to allow a greater air flow.
  • the resulting airflow can provide a full start condition for an aircraft engine initiated by the manual override interface 106.
